Answer: Option D) 1:4
Explanation:
Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.
So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.
Now, A + T + C + G = 100%
So, if adenine makes up 10% of the DNA nucleotides, then thymine is also 10%.
Then, 10% + 10% + C + G = 100%
20% + C + G = 100%
C + G = 100% - 20% = 80%
Thus, divide 80% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 40%
Ratio Adenine to Guanine is 10% to 40%
or 1:4 in simplest form
Some alleles are dominant while theh other are recessive. A dominant allele has its full effect in the heterozygote
Answer: 2.35 x 10^6 cfu/ml
Explanation:
Concentration of the original culture: ?
Dilution factor: 10^4
Colony count per plate: 47cfu
Volume of cultured plate: 0.2ml
Concentration of the original culture= <u>Colony count per plate x Dilution factor</u>
Volume of cultured plate
Concentration of the original culture = <u>47 x 10^4 </u>
0.2
Concentration of the original culture = 2.35 x 10^6 cfu/ml
You can further take the log of your answer which would be:
Log(2.35 x 10^6) = 6.371
